III. Match the words with their definitions.

IV. Study the text and try to understand all details.

1. Integrated circuits are extremely versatile because a single basic design can be made to perform hundreds of different functions, depending on the wiring of the circuits and the electronic programs or instructions that are fed into them. Most ICs perform calculations or logic manipulations in devices ranging from hand-held calculators to ultrafast supercomputers that can perform billions of calculations per second.

2. There are many other functions, however, that can be done with electronic circuitry. In radio and television receivers a primary function of circuits is the amplification of weak signals received by the antenna. In amplification a small signal is magnified to a large signal that is used to drive other circuits such as the speakers of a radio.

3. In many cases this amplification is performed with the help of oscillator circuits. Such circuits have a natural period or cycle of electrical current, similar to the natural beat of a pendulum. When driven by external signals of the same period, such as the transmission from a particular radio channel, the oscillator circuit increases its amplitude of oscillation.

4. To tune out other radio or television stations also received by a single antenna, filter circuits are frequently used. Such filters strongly reduce the signals at all but a single frequency, preventing interference among channels in a receiver.

5. These and other basic circuit types are used in a vast array of electronic devices. Consumer electronics, a field that was first developed in the 19th century with the invention of the phonograph, now includes radios, television sets, high-fidelity stereo systems, tape recorders, calculators, video games, and personal computers. Most of these devices contain one or more integrated circuits. Electronic controls have also been added to many electrical appliances such as dishwashers, washing machines, ovens, and food processors.

6. In industry and trade the computer, made up of from one to several thousand integrated circuits, has become an invaluable tool, controlling industrial operations and keeping track of voluminous business records. When connected to mechanical arms and grippers, electronics is the brain of the industrial robot that has come into increasingly widespread use for painting, welding, and assembling products that range from automobiles to watches.

7. Scientists use electronic computers to perform extremely complex calculations such as determining exactly the course of distant space probes; the probes themselves are packed with electronic instruments and communications equipment. Electronic instruments are used on Earth for scientific measurements and in the electronics industry itself to test equipment as it is manufactured. The oscilloscope, for example, is used to diagnose problems in electronic circuits, through a comparison of expected test patterns with actual results.

8. In the field of medicine electronic diagnostic instruments have given physicians a much clearer view of the human body than ever before. Computerized axial tomography (CAT) scanners, which are a sophisticated form of X-ray machines, use computers to analyze X rays and produce three-dimensional views of internal organs. Nuclear magnetic resonance (nmr) scanners analyze the response of the body's chemicals to radio waves and magnetic fields, producing maps of the body's biochemistry and clearly highlighting areas of disease.

9. Virtually all modern communications rely on electronics. Electronic circuits switch telephone calls both on Earth and in communications satellites. Satellite electronics systems amplify and retransmit television and radio communications. Computers are tied together by electronic networks.

V. Say whether the following statements are true or false.

1. In radio or television receivers a secondary function of circuits is the amplification of weak signals received by the antenna.

2. In amplification a large signal is magnified to a small signal.

3. Amplification isn’t performed with the help of oscillator circuits.

4. Filter circuits are frequently used to tune out other radio or television stations.

5. The computer controls industrial operations and keeps track of voluminous business records.
